Specification of Letters Patent.

Patented June 4, 1912.

Application filed November 25, 1910. Serial No. 594,151.

To all whom it may concern:

.Be itknown that I, RUDOLPH BALHORN, a subject ofthe German Emperor, and re-. siding at Breslau, Germany, have invented certain new and useful Improvements in Soap-Filling Machines, of which the following is. a specification. v

The present invention relates to improvements in machines for filling-in liquid soap into suitable receptacles, such as paper bags, paste-board boxes, and the like, and itconsists in the construction, arrangement and cooperation of parts to be hereinafter described in detail with reference'to the accompanying drawings, in which Figure 1 represents a front. elevation, partlyin section, of the machine, Fig. 2 shows a plan view thereof, Fig. 3 a crosssection on line AA of Fig. 1; Figs. 4 and 5 illustrate special movements for actuating driving mechanisms, and Figs. (3 and 7 represent sections through different forms of trays with soap receptacles.

The devices, now in use, for automatically running-inhotliquid soap into paper or the hke containers, meet with but little success,

in view ,of'the fact that the finished soap product presents a dead,-dull, lusterless appearance, loses its natural structure, and does not show the clearly discernible, mother of pearl like crystallization by which the hand-made roduot is readily recognized. I. have found that this is dueto faulty con-,- struct-ion and operation of the various devices now known. If, for instance, the filling device works at increased, generally hydraulic, pressure, worms or the like (when 'it is immaterial whether the discharge of the soap or the admission of it takes place under pressure) it-will be found that the natural fiuxing formation of the soap, a chemically and technically finished product in the last stage of crystallization with perfect fluXion and veinage, will be interfered with and the already obtaining crystallization will be undone.

According to the present invention there is used a pump, or a plurality of them, into which the hot liquid soapenters by its natural fall and the sucking action of the pump only. Such pumps, it is true, are'already used for recanting spirits and the like, but their'use in handlmg hot liquid soap is neW. and not obvious, .in view of thefact that so far all mechanical means for thispurpose have operated more or less unsatisfactorily,

and this was blamed rather on their use, as such, than on their faulty construction. Furthermore, it is essential that the air inclosed in the HUI-ill soap escape quickly and completely. Shaking devices with reciprocatingor swing motion did not prove a success, since we have to deal with a viscous mass,j which does not readily respond to outer mechanical impulses. I use for this purpose a shaking or hammering device which strikes the bottom of the receptacles quick and forcible blows. Lastly, provision 'had'to be madeto rapidly dispose of a charge, and I have provided for this 'purpose for automatlc, lntermlttcnt adrance of the receptacles to below the mouth of the pump.

I am well aware that several of the parts with a slanting bottom 2, so that the charge runs into the pump 3 by its own weight and the suction of the pump, in which latter a piston is vertically reciprocated. The admission of the soap int-o the pump and its discharge by the mouthpiece -8 is regulated in suitable. manner by valves, not specially shown in the drawing.

The paper bags 4: are arranged successively in frames or trays 5, movable longitudinally of the device in guide rails 6 (Fig: 3)- and advanced periodically by means of the endless chain or belt 7 below the mouthpiece 8 of the pump. The frames or trays are carried along by means of brackets 9 secured to the traveling chain. on the main shaft 10 with fast and loose pulley drive 11.is secured the toothed wheel 12 which meshes with the toothed wheel 13. fast on the Shaftlt, from which latter in, turn are mu. ated the endless chain "7, the shakers15, 15 and the pump piston.

The mechanism for shown in Fig. 4. On the shaft 14 is secured the crankdisk 16 in whose groove 17 is addriving the pump is" justably secured the crank pin 18. The pitman "19 ispivoted to the collar 20, slidable on the rod21 and carrying the nut 22 for the screw spindle 23. The rod 21 is secured above to the one arm 24 of a bell crank lever, pivoted. at 25, whose other arm 26 provided with a slot 28 in which takes the pin 29 of a rod 30 (Figs. 1 and 3). This rod 30 is pivotally secured to the pump gear,

consisting of the two vertical guide mem-' bers 31, 31 and'the two cross members 32,.

32. The bell crank lever also carries the journal 27 for-the screw-spindle 23 with handle 34. V

, Upon rotation of the shaft 14, the rod 21 will oscillate from the solid line position into the dotted line position and vice versa and thereby cause the piston rod 33 of the pump to reciprocate vertically. For roughly adjusting the pump lift the crank pin 1.8 is shifted .in its groove, 17 and for finer adjustment the handle 34 is turned. The set screw 85 insures the desiredposition of the loose collar .20 on the rod 21. By rotating the piston rod 33, the piston is adjusted within the casing,.which latter is preferably jacketed and heated for preventing the contents from congealing. In this manner the piston can always be made to dcscciul clear to the bottom of the casing to prevent formation of dead spaces in which liquid soap could collect.

For actuating the endless chain 7 with its accessories the crank disk 36 isused, which is keyed on the shaft 14. In a'manner simn larto that just described with reference to" the pump drive the crank pin 38, adjustable in the groove 37, is 'pivotally connected to travel of the chain depends upon the angle of oscillation of the bell crank lever 43, 44. s

For varyingthe advance of the chain the pin 38 is adjusted in its groove 37 and the collar 40' on the rod 41. This adjustment is necessary in order to be able to use the same device with difierently sized receptacles, as shown in Figs. 6 and 7. For operating the hammering rollers 15, 15v their shafts 49 carry sprocket wheels 50,53, which are connected t-o-the toothed wheel 51, fast on shaft 14, by means of the driving chains 52,

and 54. These hammering devices strike the bottom of the receptacles or the trays violently and in quick succession.

The described machine may be run by hand or power. The endless chain is preferably of such length that the filled rec'eptacles can be run directly into a cooling chamber or the like. Instead of a. single pump, as described, it is-obvious that a number of them may be used side by side,-

when the endless chain must be of a width to receive a corresponding number of receptacle trays, placed alongside oneanother. What I claim and desireto secure by Letters Patent is I In a device of the character described, the

combination of a pump for periodically dis: charging viscous liquid, adjustable means for regulating the extent of the piston travel of said pump, means for admitting the viscous liquid to said dischargingmeans by its own gravity and the suction of the pumponly, and means for intermittently feeding trays carrying receptacles up to and away from the discharge opening of said pump,

means for regulatmg the extent of s'ald 1ntermittent feeding movement, and hammering means, striking the filled receptacles from below, the parts all constructed, arranged and cooperating substantially as set forth.

In testimony whereof I affix my signature in presence of two witnesses.
